Anyone handloading for there's? I shot mine for the first time and the brass was landing at the 40 yard line. I assume it is overgassed?

What powder types are appropriate for handloading?

Thanks
 
36-37grs of IMR 4895 -Hornady 140gr Interlock works okay.
Still hard on brass. Not done testing yet.
I think I'd stay with hand loads only.
And try and keep it under 2600 FPS 39,000-40,000 cup

Hope other will chime in too.

The AG-42 was from the beginning overgassed as it is designed to run on two different pressure loadings with only one gas setting.

In service they would do stuff like oiling the cartridges (not a good idea) to make up for deficiencies in the design. Likely you will have to play around to find what is actually the ideal loading as I don't think it was optimized in service.

Would the 140 gr bullet be best? Looks like they used a 156 gr then switched to 140?

This is a learning curve for me to. Each rifle will be different. Shooting store bought ammo I believe will have too high a pressure and really put a strain on all the gas train. Might even damage it.
Figure out your pressures of your load. Start soft (under 40,000cup). Check your FPS and work from there.
You need a Chronograph.
I had a Caldwell Ballistic Precision Chrony had lots of trouble then I got a F1 SHOOTING CHRONY®
 
Here is my pet load for mine, works great zero issues.

Hornady 140 grain Interlock
Powder IMR4895 34.5 grains
Primer Winchester Large Rifle
Case Winchester Trim length 2.157 "
COL 3.03 "

No pressure signs and ejected great, super accurate for me. There is an adjustable pressure gas plug I think.
 
NEVER use this rifle with the 156- or 160-grain slugs, NOR with the Norma-Oslo sealing ammunition which is so common in 50-round boxes on the East Coast; it was designed specifically for the 1941 load, which used a 139.

The rifles were deliberately overgassed in order that they would function at temperatures of minus-40.

The direct-impingement non-adjustable gas system means that you CAN install a set-screw at the Gas Block in order to LIMIT the amount of gas getting to the Carrier.

Swedish Armourers had a KIT consisting of a special tool and a range of Gas Orifices which were to be installed in the Exhaust end of the Gas Tube. These kits seem never to have been surplussed and are about as common as nice-smelling Lutefisk.

Nice thing about this oddball rifle is that, once you get it running, it is likely the most accurate out-of-the-box semi-auto rifle you will ever find.

It was designed to use both rounds, for evidence I submit the fact the sight adjuster on the rifle has a M94 and M41 trajectory settings. It wouldn't have both if it wasn't intended to be used with both
 
I have two of these rifles and found IMR 4350 and IMR 4895 work well with the 140 bullet. With the IMR 4895 I was able to reach 2600fps. REMEMBER TO RESIZE FULL LENGTH.
Very accurate semi's.

Also before I forget always use the hardest primers you can find NOT FEDERAL. I had a out of battery detonation with a AG-42b and Federal ammo.
